Google translator API ( PHP 5 class )

---

June 5th, 2007 by paolo

This PHP 5 class API is developed on the base of a tool that I wrote some years ago.
Simply works querying Google translation tools with the text and language pair choosen.
I find it useful because of Google haven’t released yet an API for its translation tools.
Here the code!

<?php

class Google_API_translator {
    public $opts = array("text" => "", "language_pair" => "en|it");
    public $out = "";

    function __construct() {
        echo "Google Translator API\n(c) 2007 Involutive snc http://www.involutive.com\n";
        echo "Author: Paolo Ardoino < paolo@involutive.com >";
    }

    function setOpts($opts) {
        if($opts["text"] != "") $this->opts["text"] = $opts["text"];
        if($opts["language_pair"] != "") $this->opts["language_pair"] = $opts["language_pair"];
    }

    function translate() {
        $this->out = "";
        $google_translator_url = "http://translate.google.com/translate_t?langpair=".urlencode($this->opts["language_pair"])."&amp;";
        $google_translator_data .= "text=".urlencode($this->opts["text"]);
        $gphtml = $this->postPage(array("url" => $google_translator_url, "data" => $google_translator_data));
        $out = substr($gphtml, strpos($gphtml, "<div id=result_box dir=\"ltr\">"));
        $out = substr($out, 29);
        $out = substr($out, 0, strpos($out, "</div>"));
        $this->out = utf8_encode($out);
        return $this->out;
    }

    // post form data to a given url using curl libs
    function postPage($opts) {
        $html = "";
        if($opts["url"] != "" && $opts["data"] != "") {
            $ch = curl_init($opts["url"]);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_HEADER, 1);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
            curl_setopt($ch, CURLOPT_TIMEOUT, 15);
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $opts["data"]);
            $html = curl_exec($ch);
            if(curl_errno($ch)) $html = "";
            curl_close ($ch);
        }
        return $html;
    }
}
?>

<?php

$g = new Google_API_translator();
$g->setOpts(array("text" => "ciao", "language_pair" => "it|en"));
$g->translate();
echo $g->out;
?>

   Usefull class. I think that google never released an API because the service is provided “as is”. The translations aren’t very good…

   I know that translations are not so good, but in next days we’ll post a good idea for exploit Google translations ( is is based on a tool I made some time ago ) ;)

   Hello
   Thanks for the valuable script.
   I have used your script.

   but is it possible to display the result from my site?
   I mean i send request to google for translation and receive the translated value through curl , then display the data to my site?

   Hope you can only person who can give the solution.

   Regards
   Shahed

   Yes, of course you can, but only if your hosting allows outgoing connections with curl.

    I used an equal approach on translating strings through google.
    After several hundred requests i got a HTTP403 error.
    It seems like google doesn’t want anymore requests from my server and suspects an atttack.

    Does anyone of you know a solution to this Problem?

    Thanks,
    rob

    For use throught proxy:

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_PROXY, “http://your.proxy”);
    curl_setopt($ch, CURLOPT_PROXYPORT, 8080);
    curl_setopt($ch, CURLOPT_PROXYUSERPWD, “user:pass”);
